Abstract (en)
[origin: US7967815B1] Cryosurgical instruments and methods utilizing improved heat transfer characteristics. A cryosurgical device includes: a tubular housing; a cryogen supply passage; a heat exchange enhancing member in the housing, disposed along a longitudinal axis of the housing; an annular cooling passage between the heat exchange enhancing member and the tubular housing; a tip cooling and cryogen flow directing section that transmits a temperature of a cryogen flow to the tip, and an insulation element in the tubular housing.
